A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?

Choice A rationale:

Verapamil is a calcium channel blocker and is expected to decrease heart rate by inhibiting calcium influx into cardiac cells, particularly in the SA (sinoatrial) node, where it can slow down the heart's electrical impulses.

Choice B rationale:

Increased contractility is not an expected outcome of verapamil use. In fact, verapamil's main action is to decrease myocardial contractility, making it useful for treating conditions like angina and atrial fibrillation.

Choice C rationale:

Verapamil is known to dilate coronary arteries, which can improve blood flow to the heart muscle and relieve symptoms of angina.

Choice D rationale:

Reduced blood pressure is an expected outcome of verapamil use due to its vasodilatory effects on peripheral blood vessels. This can be beneficial in treating hypertension and angina.

Choice E rationale:

Relieved chest pain is an expected outcome of verapamil use, particularly in the case of variant angina (Prinzmetal's angina), as it helps to relax coronary arteries and reduce coronary artery spasm, which is a common cause of chest pain in this condition.

Choice A rationale:

Checking the femoral site for hematoma formation is the most appropriate action in response to the client's complaint of pain at the right groin insertion site after a cardiac catheterization. Hematoma formation is a potential complication of this procedure and can lead to further complications if not addressed promptly. Checking for hematoma allows the nurse to assess for bleeding and take appropriate measures to manage it.

Choice B rationale:

Stimulating the client to take deep breaths is not the most immediate action needed in this situation. While deep breathing is important for respiratory function, the client's pain at the groin site requires immediate assessment to rule out complications.

Choice C rationale:

Evaluating the integrity of the IV insertion site is not the primary concern in this case. The client's pain is localized to the groin site, which is where the cardiac catheterization was performed. Checking for hematoma formation at this site takes precedence.

Choice D rationale:

Assessing distal lower extremity capillary refill is important for assessing peripheral perfusion, but it is not the most immediate action needed when a client complains of pain at a specific site, such as the right groin insertion site after a cardiac catheterization. Checking for hematoma and assessing for bleeding should come first.
